FLUSHING DEVICE.

- Specification of Letters Patent.

Patented ma 13, 1909.

Application filed August 18, 1908. Serial No. 449,125.

- To all whom it may concern:

Be it known that 1, Funnels F. IIAWIUNS,

- a citizen of the United States, residing at lroy, Rensselaer county,New York, have invented a 116W and useful linprm'ement in FlushingDevices, of which the following is a specification.

' My invention relates to [lushin' devices for furnishing anintermittent supply of liquid for flushing, scouring or like purposes.

It is particularly adapted to flush tank's used in connection with waterclosets, hoppers, latrines and the like. its object is to provide adevice that shall be simple, economical and durable in construction, aswell as ellicient and noise-less in operation.

1 will show and describe certain lorms of my device, it being understoodthat these may be modified within considerable limits in the practicalegnbodiment of my invention.

In the drawings, Figure 1 is a side elevation, partly broken away, ofone form of my device; Fig. 21s a vertical section through the plane 2-'2, Fig. 1 ,Mg. 3 is an enlarged view, partly broken away, of the valveof Figs. 1

, and 2; Fig. 1 is an enlarged front elevationot the same valve; Figs. 5and (3 show another form of the device, Fig. 5 bein an elevation withthe front wall removed and Fig. (3 a Fig.

horimntal section through the plane t' -=6, Fe. 7 is a transversesection ol' the D .I. tank 01 1' 1g; 0, showing a modnled shatter, the.section plane being. unheated by the line 7--7,- Fig. 5.

.l'tel'erring to the first four hgures, '1 dos1gnates a closed tank ofcyhndric lorm, bavnre a vertically extending, radialpartition 12, to

which is hinge-d a movable. radial partition 13, shown as provided oneach of its laces with a plug 1-1, which may be of rubber or likematerial. Passing through the wall of the tank 11 on opposite sides otthepartition 12 are branch pipes 15, 16, whose open ends are adaptedtie-engage with and be c osed by.

the plugs 14. The other ends of thelpipes 15, 16 pass into 0 positesides of a our-way Valve 17, Whic is also connected with an inlet pipe18 and an outlet pipe 19. 'lhe ilug 20 of the valve 17 has a stem 21, onthe lrce end of which is mounted a four tooth ratchet 22, with which chnges a pawl L3, pivoted on a lever 24, which is il'sel pivoted on theshaft or stem 21. A spring normally holds the lever 21 in its upwardposition, shown in Fig. 2. From the free end of the lever 2 1 depends achain 26, by which it may be manna ly operated.

The operation 01 this term of my device is as follows. It is of courseunderstood that anti-clockwise, until the plug 14 closes the I end ofthe branch pipe 16. Then if the lever 24 be pulled down by the chain 26,the plug 20 will be rotated one-(punter turn to the position shown indotted lines, Fig. 3. The inlet pipe 18 will then be (onnected with theleft branch pipe 115, the branch pipe 15 being simultaneously connectedwith the-outlet or discharge pipe 1t). The water flowing mat the leltol' the partition 12 will then swing the partition 12; to the right,driving out all the water in the tank, without loss of pressure, throughthe pipes 15 and 1.9. When the operator releases the chain 26, thespring 25 will return the lever 24 to its normal position, leaving thetank ready tor aseeond simultaneous lilling and emptying, the directionsof motion being the reverse of those last described.

lhe 'l OIIILO'i my device shown in Figsf5 and (3 ol' the drawingsdillers from that already described chiefly in its shape and in the butthat the movable partition swings on a vertical axis. As shown, one wallis in the form of a semi-circle with short tangential extensions. Thetank 31 has a narrow stationary partition 32, to which is hingedthopivoted partition :53, which swings nearly or quite in contact with thearc-shaped wall'of the tank. vided' with plugs 34 to close the ends 0the branch pipes 35 and 36. The connection of' these branch iipes withthe l'our-Wa valve 37, as well as t e connections of the in ct pipe 38and the discharge )ipe 39 are similar to those above described. Themovement of the valve plug is modified by securing-to its As before, thepartition 33 is ro-- stem 1 1 a two-armed lever -12, toeaeh end of fit,so that one or more or" its bleechholes, so that the Water confinebetween the partitions l2 and. 33 may esrnlpe,

that the operation the device will altered; except that the valve plug"i reeiprocstory n15 vemeul ed step-by-step motion of lhe first Inaddition, the portilion 33 b ent of gravity, will more w t removed fromthe wail of the the in'llowing Wafer will p: Without practicallyrelm'dii and in no Wise lessening the (allergen in this W213; s ten-ii vsmell capacity and consequent ch' may be caused to oeliver my 100% morethen it notes" the movable partition is e p #0 I one, it cannot, byreason of is reduced be caused to cramp or bind in the tar Nhere,however, the movshlo purfiitien which for convenience I may designateshutter, is fitted to the Well of the tank, as in Fig. 2, it may beadvantageous to pierce the branch pipes 15, 16 within the tank ith smallholes 27 to serve as Washers thus allowing the full were pressure to noton'the shutter 15, thereby holding the plug 14 in still more secureContact with the end of the branch pipe.

In Fig. 7 of the drawings-I have shown additional ediustsblemeens forincreasing the delivery or Water from the tank. This is accomplished byproviding the shutter 33 with an aperture 51, Wholly-or partly closebleby a gate 52, sliding in guides 53, and conveniently provided with aknob or handle 54. Toperrnit the adjustment oi the gain 52, the frontwell of the tank 81 may be provided with e tightly clossble aperture,not shown in the drawing, as the provision of such aperture is easilywithin mechanic.

By reason of'jhe compactness ofniy do vice, especially Where the shutteris loosely lit-ted in the tank; of iisrequiring min iinuin of attentionor repair end of the first that its act-ion is substzintie-l lyindependent of grsv li y, it may be placed in any desired relation tothe closet or vessel-to be flushed or it may he the skill, the
